Defeating smallpox, ozone layer depletion, HIV/AIDS and hunger - humankind *is* good at solving problems collectively. Gaining control of climate change, via renewables, is next. Noteworthy that 🇨🇳 and 🇪🇺 take the driver‘s seat.

The EU condemns the U.S. travel restrictions against European citizens and officials. Such measures are unacceptable between allies, partners, and friends. The EU stands firm in its defense of freedom of expression, fair digital rules, and its regulatory sovereignty.

Good question. 👇🏼 They find that the „green“ wage premium in Norway is larger for the low-skilled than for the high-skilled, and on average lower than „brown“ (fossile) wage premia.

Trying to honor s/o with an institution name that is grammatically inappropriate? It clearly has one "The" too many.

This is one of the best papers that I've read this year! It demonstrates the power of bringing rigorous modern empirical methods to bear on the intuitions developed by previous generations of social scientists -- in this case Bourdieu. It also helps us soumitrashukla.github.io/making_the_e...

Many commentators look for the bad news in this. But by far the most important thing is that 🇺🇦 gets the 90bn. (And the mechanism of a 🇪🇺 loan is also interesting.) www.theguardian.com/world/live/2...

Our dept is hiring an associate professor in microeconomics / competition theory. It is a wonderful department - do get in touch. The job ad is in German but we teach more and more in English, so we‘re flexible. www.hu-berlin.de/en/universit...

The pattern: certain truths would only disrupt, they must therefore stay dormant. The opposite of what science should do for society. A pattern that appears often, even in sober 🇩🇪. In 🇺🇸 it is now an unconcealed strategy of the gov‘t?

Good to be rid of rigidity

EU energy synchronization - nontrivial but a big-ticket item

🇩🇪 can be proud of being incorruptible. No public servant fills their own pockets. But when we let them, they fill their friends' pockets. Is this acceptable? 👇🏻 Recent SZ article by @basbrinkmann.bsky.social on a Bundestag committee. www.sueddeutsche.de/politik/bund...

"often overlooked that the existing law provides a solid foundation for the decarbonization of the building sector" Informative and very short article. 👇🏼 Also easy to overlook: that the inclusion of the building sector as an element of 🇩🇪's climate strategy was a big step forward.

I only recently learned that the first significant antisemitic massacre in Europe was in France and the Rhineland, 1096 by Crusaders who took a detour on their way to the Holy Land to slaughter 2000 Jews. We keep thinking it’s past history but it never seems to be. en.wikipedia.org/wiki/Rhinela...

We conducted a 10-year follow up on our impact evaluation of Rwanda's electricity access roll-out program - now out in @natcomms.nature.com. Modest short-term impacts sustain, but connection rates stagnate and electricity usage remains on extrenely low levels. www.nature.com/articles/s41...

This looks like a most interesting PhD program for e.g. econ students with climate interests.

Full investigations of all possible wrongdoings - important to keep the public sector strong and free of corruption. (Here, a group of former public servants in Radio/TV are charged with embezzlement in an old but prominent case, regarding payments of about 1.5 million EUR.)

Congratulations, Lavinia and Virginia! A very significant best paper award.
